YouTube can be a funny, strange and at times silly place, and video game culture delivers some of its quirkiest videos as talented animators and directors mess around with gaming conventions. With such a prominent history in the industry, Nintendo naturally features in plenty of cameos and mash-ups, occasionally to brilliant effect.

The latest example we've come across is Super Mario Slug X, which takes the Nintendo mascot and imagines a scenario where he's the hero in a Metal Slug game, the classic Neo Geo series. Not content to stop at that, GameBill Studio has thrown in some other references to pick up, including Street Fighter, Dragon Ball and more besides that we'll admit we can't identify.

It's all done by taking existing pixels and game assets and fusing them together, and we think the effect is pretty darn entertaining.
